NewAmsterdam Pharma Announces the Appointment of Juliette Audet as Chief Business Officer

NAARDEN, the Netherlands and MIAMI, April 1, 2024 — NewAmsterdam Pharma Company N.V. (Nasdaq: NAMS or “NewAmsterdam” or the “Company”), a late-stage, clinical biopharmaceutical company developing oral, non-statin medicines for patients at risk of cardiovascular disease (“CVD”) with elevated low-density lipoprotein cholesterol (“LDL-C”), for whom existing therapies are not sufficiently effective or well-tolerated, today announced the appointment of Juliette Audet as Chief Business Officer (“CBO”), and her simultaneous resignation from the Company’s Board of Directors, both effective April 1, 2024.

“We are privileged to welcome Juliette to our management team as CBO,” said Michael Davidson, M.D., Chief Executive Officer of NewAmsterdam. “Juliette has been a trusted advisor to NewAmsterdam as an investor and member of our Board of Directors since 2020, and brings a unique, multi-faceted perspective to her new role, in addition to over a decade of experience in senior leadership roles in the biopharmaceutical industry. We look forward to her continued contributions as she transitions to her new role, and further supports our efforts to mature into a global, commercial organization.”

“I am thrilled to take on this new role among such an esteemed team of pharmaceutical, business, science and medical leaders committed to transforming the standard of care for people at high-risk of cardiovascular disease,” said Ms. Audet. “I believe NewAmsterdam is well positioned to achieve this mission in the near-term, with two pivotal readouts for obicetrapib expected this year, and progress ongoing to build a commercial organization that can effectively bring this oral, low-dose, once-daily CETP inhibitor, if approved, to millions of underserved patients globally. I am eager to collaborate with my colleagues to deliver tremendous value to patients and their families, as well as our shareholders.”

Ms. Audet is a seasoned life sciences executive and investor with extensive pharmaceutical business development, finance and operational expertise. She was most recently a Partner at Forbion, where she was part of the team that built NewAmsterdam Pharma, and played a key role in out licensing obicetrapib, setting up operations and recruiting the management team. Prior to joining Forbion, Ms. Audet was a principal at the Novartis Venture Fund based in Cambridge, MA. She also worked at Novartis AG for their commercial division and at McKinsey and Company focusing on Pharma and Biotech.

She earned her M.B.A. with distinction from Harvard Business School and her M.Sc. in Physics from EPFL (Lausanne, Swiss Federal Institute of Technology).

About NewAmsterdam

NewAmsterdam (Nasdaq: NAMS) is a late-stage biopharmaceutical company whose mission is to improve patient care in populations with metabolic diseases where currently approved therapies have not been adequate or well tolerated. We seek to fill a significant unmet need for a safe, well tolerated and convenient LDL-lowering therapy. In multiple Phase 3 studies, NewAmsterdam is investigating obicetrapib, an oral, low-dose and once-daily CETP inhibitor, alone or as a fixed-dose combination with ezetimibe, as preferred LDL-C lowering therapies to be used as an adjunct to statin therapy for patients at risk of CVD with elevated LDL-C, for whom existing therapies are not sufficiently effective or well tolerated.
